CONTROLLING- MECHANISM FOR HARVESTERS.

Application filed .July 19,

To ZZ fio/20m t may concern:

lie it known that l, BERT BENJAMIN, a citizen ot the United States, residing at @ak Park, in the county of Cook and State-ot illinois, have invented certain newrand usctul Improvements in Controlling Mechanism 'for Harvester-s, of which thev following is a full. clear, and exact specification.,

Mv invention relates to controlling` mechanism for harvesters and machines o1 like character.

ln the usual type of harvester now in use7 various adjustments are provided for; sucu,

tor instance, as the tilting of the harvester. f

. raising and lowering of they reel, shifting or the binding mechanism, and control of the bundle carrying mechanism.

At the present time it is becoming more and more common to use power units or tractors to propel harvesters in the field, and unless an additional operator is to be employed, it becomes necessary to fprovide operative connections between the harvester and the power unit or tractorwhereby al single operator may control the harvester adjustments from the tractor.

At times during the operation of the machine it is necessary or desirable that a plurality of adjustments be made simultaneously; for instance, in operating a harvester in short grain, the harvester should be tilted and the reel should be lowered in orderto cut more straw and to properly deliver thev straw to the platform apron.

One object of the present invention, therefore. to provide a construct-ion whereby the harvester and the operative elements carried thereby, may be adjusted from a plurality of locations, as for instance, from the operators seat on the harvester, or from a suitable position on the tractor.

l A further object is to .provide improved controlling means for the harvester and for the operative element-s carried by the harvester whereby a plurality ot adjustments may be made simultaneously.

A further object is to provide means whereby a plurality ot simultaneous adjustments may be made either from the harvester or from the tractor.

One embodiment of my invention is illustrated in the accompanying` drawings, and in these drawings v Figure 1 illustrates in side elevation along line 2-2 ot' Fig. 2 the rear end of ati-actor construction the draw bar .means of a lever 1918. serial No. 245,725. Y

and the front end of a harvester showing the operative connections between these two v machines for controlling the various adjustments of the harvester;V Y l? is a front elevation along line 1--1 ot Fig. 1 of the front end ot a harvester, the` connections between the `harvester and vthe tractorV being shown in section.

The harvester illustrated inV connectionv with my invention is providedV with the usual frame 10, lharvester wheel 11, platform frame 12, elevator frame 13, binding mechanism 14, bundle carrier 15, and reel support 16. Vertical standards 17, 18 and19' of any1 suitable construction are rigidly secured to the frame of the harvester, the standard 1T supporting the binding mechanism 14 which is carried by the binder pipe 2O which in turn is adj ustably mounted upon the support 17. The standards 18 and 19 carryv the reel supporting bracket 16 which is rotatably mounted'upon a shaft 21 carried at one end by a bracket 22 secured-to the standard 18, and at its opposite end by the usual seat pipe 23 supported on standard 19. A bracket 23 is carried by the pipe 23 and supports the usual seat (not shown). In Vmy improved 24carried by the tractor 25 is connected by means of a draft member or tongue 26 to the frontend of the harvester frame as shown at 27;' The har-V vester is provided with the usual tilting' mechanism which operatively connected to a shaft 21. This shaftl is oscillatedfby 28 which is secured thereto` and is provided with the usual pawl locking' mechanism which cooperates with. the toothed sector 29. The shaft 21 supported on bracket 22 and seatV pipe 23 has secured thereto and projecting forwardly.therefrom, a crank arm 30, `which is connected by a' link 81 to an arm 32 secured at one end to a tubular member 33 turnably supported` in brackets 34 and 35 carried by the draft member 26. The opposite end of the arm 32 is connected byV means` of an adjustable link 36 to the supporting bracket forthe reel. which, as above stated, is turnably mounted on the shaft 21. The front end of the tubular member has rigidly securedtheretc a reelsupporting c to a lever' 43 by means of' ay rod; 4:4', the usual `pawl and sector locking means for this liever .s memberis provided at its forward end withy afiever 57 :havin-0f lthe usua-llocking means, and by means or which 1t may be manipu- Y essary.

VThe with respect to y bracket 16 is also connectedbei-'ng` 'also providecxif. ACounterbalancing means 'is secured at one end'to the scat pipeZB and at its opposite endyto the reel supporting bracket 16.

I Vlrhe usual adjusting shifting mechanism is ,also providedV and is shoivnpat fil-6, this lever being connected by meansof a rod 47 to a crank 48 formed' at one endl of a rod" 49, the opposite endl of the rod Li9 havinga crank 5G'connectedE by a link 'ji tothe reciprocable carriage upon which tlie'bi-nding mechanism is 4supported in the usual manner. YThe rod a9 is4 j ,ournaled in suitable bea-rings 52' carried the to the machine frame. A connection. vis also providedwhereby the y bifnd'ershifting mechanism may be operated` from the rear of the tractor, this connection yincludingV an arm r53 secured to the rod 4,9; and yconnected by means of' a" link 54 to crank arm 55 carriedaby-a tubular memberfd This tubular lated from the seat of they tractor.

The connections for 'controlling the po sitionv of the bundle carrier include a rod suitable bearings on the 19- 'and connected atene end by means of a link 6 tothe bundle carrier, and at its opposite end provided with a treadle Glfby means of a'link 63, bywhich thecrank and rod bundle carrier.

' The bundle, carrier mechanism illustrated is shown merely for Vthe purpose of' disclosing'a; practicaly embodiment of' my invention', and is identicalyin construction with that` illustrated in Patent Baker-,issued November 18, 1890; Since no nove'itv is claimedper se in the bundle carrior meci'ianism, a'more complete illustra# tion ,of this ,construction is not? deemedne'c- *"lhe rod carrier is controlled, operative connections is also provided with by means ofwvhich it may be manipulated from the rearof thek lever 41 of the: usual construction is connected with the link lever for the binderA tui-nis connected to a foot No. tiene? te.

5B Vbymeans of' which the-'bundle y tractor, and these connections yinclude a crank 64 connected by a link 65 and arm 66 toa rod 67 which in turn extends through the tubular member 33 and is provided; on` its Afron-t endwi-thian upwardly extending' arm G8, this arm having` a forwardly eX- tending. projection. or' handle 69 disposed adjacent the seat of the tractor. t

The operation ofthe Various parts of the mechanism above described will belnow set forth.

From the description given above it will,

b e seen that theV binder shifting mechanism, raising andl reel, bundle, carrier adjustment, and harvester tilting adjnstinent, maybe made from either of two positions, vii-:4 zvr fromythe position ,onI the harvester frame, a Yiosition on the tractor frame. Assuming that the adjustmentsare tov be made from theA seat of the tractor, the binder shifting loyer andthe lever for raising and lowering the reel located on the harvester should be adjusted V for free tioating movement on. their pi-vot by using` some suitablel means s'uch as thev rings 70 shown.11i-'Figl 1, to hold the pawls out of locking engagement with their corresponding sectors.

lfvllien this has been` donethe` correspondinglevers( disposed adjacent the seat on the. tractor may be manipulateda lf' the harvester is beingoperatedfin` short grain. or in tangled. grain andi it ifsdesiredto lower the. reel: and tilt the harvester downwardly, loweringthe cutter bar,'the leveris shiftedr ljateralla' with respect to the. line of draft, and byv means ofthe combined linkconnections from the. arm. carried by the"V tubularmember which.v isconnected" to. the'v lever 37;, Vthe harvester isY tiltedV andi the reel is Rocking offA theV shaft 33. thus. is

whichl in turn pulls the leven 30 rigid with the rock shaft-213. rlllii'sflatter,rock shaft, however, is heldagainst rocking` movement by.v the liover- 28 locked to the toothed. sector 29. fas

the sha-ft 211" is locked against rocking mover ment this force is applied in av downward directionV on the shaft 38l bracket ,34; resulting in breaking the pivotal' connection betweenthe platform anddraft member 26A whereby# the entirfeharvester frameL is bodily lowered. ylnX raising. the reel and platform` the reverser movements are effected by rocking the in an anti-clockwise direction.. The lever' Y is swung laterally to adjust the binding At thev same. timeA the lever mechcarried in the anism forwardly and backivardly on theY within easy 'reach' of the operator of the` tractor, and since these levers are mounted for lateral movement, their adjustment may be easily and quickly made Without interrupting the progress of the tractor and the trailing machine.

In order to disconnect the harvester or trailing machine from the tractor it is necessary merely to disconnectI the link connections 8l, 86, 54 and 65 and the harvester may then be operated as a separate unit.

From the above description it Will be seen that a simple and efficient construction has been provided for accomplishing' the desired. purpose, and a constructionhaving few parts and by means of which the Avarious adjustments may be made quickly and eX- peditiously.
